European Union antitrust regulators have confirmed that they had received Microsoft's complaint against Google and will seek further information from the Internet search company.

Microsoft claims that Google used its dominant position in the search market to restrict the growth of Microsoft services.

However, Google said it was surprised by the action and said it would happily explain itself.

In a detailed blog, Microsoft's general counsel, Brad Smith, outlined the company's grievances.

"Our filing today focuses on a pattern of actions that Google has taken to entrench its dominance in the markets for online search and search advertising to the detriment of European consumers," he said.

Among the grievances are the following:

- Using technical measures to stop Microsoft's search engine Bing from indexing content on Google-owned YouTube.

- Blocking Microsoft Smartphones from operating properly with YouTube.

- Controlling access to online copies of out-of-copyright books.

- Limiting the ability of businesses to reclaim "their own information" generated through Google advertising campaigns for use elsewhere.

- Compelling leading websites to only use Google search boxes on their pages.
